Salinity Gradients for Sustainable Energy: Primer, Progress, and Prospects

Environmental Science & Technology, 2016
Combining two solutions of different composition releases the Gibbs free energy of mixing. By using engineered processes to control the mixing, chemical energy stored in salinity gradients can be harnessed for useful work. In this critical review, we present an overview of the current progress in salinity gradient power generation, discuss the ...
